CIRCUIT-CLOSER FOR LETTER-BOXES.

Specification of Letters Patent.

Patented June 29, 1920.

Application filed August 14, 1919. Serial No. 317,433.

To all whom it may concern:

Be it known that I, Finn) BACHILA, machinist, a Russian subject,residing at 1114 Demontigny street, in the city of Montreal, in theProvince of Quebec, in the Dominion of Canada, have invented certain newand useful Improvements in Circuit-Closers for Letter-Boxes; and I dohereby declare that the following is a full, clear, and exact description of the same.

The present invention relates to improvements in letter boxes and themain object of this invention is to provide a device of this characterthat will signal or ring a bell when a-letter is thrown inside and thusinform the residents in apartment houses that they have received theirmail.

To better understand this invention reference should be had to theaccompanying drawings in which:

Figure 1, is a front elevation of a series of letter boxes as usuallyinstalled in apartment houses.

Fig. 2, is a vertical sectional view of the invention illustrating theelectrical contacting device.

Fig. 3, is an enlarged perspective view of the invention illustratingmore clearly the electrical contacting device for a bell or any suitablesignal.

Like numerals of reference indicate cor responding parts in each figure.

In the drawings 1, represents a casing provided with a hinged door 2having a slot or rectangular opening 3 at its upper end. Provided overand adapted to close said opening 3 is a plate 4 mounted on the springhinges 5.

Above said opening 3 adjacent one end thereof on the door 2 is rigidlysecured a contacting member 6 whichprojects downwardly over said plate4: to one end of which is connected the electric wire 7. Said member 6is made to contact with the -U shape member 8 which is rigidly securedto the plate 4, when said plate is swung open the drawings.

It will readily be seen that when a letter is pushed through the opening3, the plate which closes said opening, is pushed in-' wardly, thuscausing the U shape member 8 to contact with the member 6 and form acircuit which will ring a bell or any suit-- able signal.

On the inner side of the door and secured thereto is provided a letterbox 10 in which the mail matter will drop.

,What I claimas my invention is:

A circuit closer for letter-boxes, comprising a casing having an openingtherein; a hinged door provided over the opening of said casing; aletter-box secured on the nearer side of said door; a letter. openingprovided in said door; a hinged closing plate provided over saidopening; a U-shaped contacting member electrically connected and securedto said plate; a downwardly projecting electrically connected andcontacting member secured adjacent said plate, said member being adaptedto project slightly outwardly from said plate whereby when mail-matteris pushed through said opening, the closing plate will be opened and thecontacting U-shapedmenr ber, 011 said plate, will be made to contactwith the downwardly projecting contacting member and cause an electricalcircuit which will give a signal, substantially as described.

Signed at Montreal, Canada, this 17th day of July, 1919.

FRED BAGHILA.
